Fig.1. Rolled 8 % elemental resistance (6 - 8 %), next upgrade to 11 % :ok_hand:
Fig.2. Rolled 11 % ER (9 - 11 %), next upgrade to 14 % :thinking:
FIg.3. Rolled 14 % ER (12 - 15 %), next upgrade to 19 % ā€¦
Fig.4. Rolled 19% ER (16 - 20 %)

What I was hoping for was for the ER to be 15% at Figure 2.
However, for some reason, 14% was presented.
This seems strange to me.

Is Glyph of Order working correctly?

I was considering combining it with Rune of Evolution in Season 3, so Iā€™m very curious as to whether this is intentional.
